Abstract: High voltage switchgear, as an important device for controlling and protecting electrical equipment, is an indispensable distribution equipment in the power system. Its performance and safety are directly related to the stable operation of the entire power grid. Therefore, after the installation of the equipment is completed, conducting a handover test on the high-voltage switchgear is not only the key to verifying that the various performance indicators of the high-voltage switchgear meet the design requirements and relevant standards, but also an important link to ensure the safe and reliable operation of the equipment. Based on this, conducts handover tests on 7 newly installed 20 kV high-voltage switchgear in the high-voltage room of the Huangpu graduate school center of Guangzhou university, to ensure that the high-voltage switchgear can operate safely and reliably after being officially put into use, and to ensure the stable power supply of the power system.
